4 Claims.

My invention relates to improvements in ice anu a tur ng sy t ms in whih c ar i is ohtained by using raw water and agitating the water byintroducing air under pressure to the cans containing the waterduringthe freezing operation.

The invention in this application, which is a partial continuation of myco-pending application, S rial Number 5,65 led Ju l93l, relates to thecontrolling of the ll between the air supply pipe and the flexibleconnections with the drop tubes of the cans, whereby the controllingmeans is located within convenient reach of the operator.

The object of my invention is to provide an air controlling hosecoupling adapted to be connected directly to the air supply pipe of theair circulating system.

A further object is to provide an air controlling-hose co lin with inleand Outlet shank for connecting the coupling with the air supply pipeand with a flexible hose, which in turn may be detachably connected withthe drop tube of the individual ice cans.

A further object is to-provide an air control.- ling hose couplinghaving a valve embodied therein for controlling two volumes of air toeach drop tube.

The b dy 6 is al providedwith a tubular outle an ha in dqrru ations 3,3 for the attachm rit ofthe ible hose 21.

h body 2 i provi ed with a cylindrical he or va ve chamber extendintransversely relatively to the length of the shanks 28 and 32. T a waysof which shanks communi- G te with a d mber 35.

A ylindri a valve stem 36 is ta ahly m unt.- ed in e here, r ham er 35.of the body. for opening or closing the passage between the shanks 28and 32. Said stem 36 is provided with lar ad al apertures 38 and 39 foming a large passa eway throu h the st m. The s m may be rotated bymeans of a handle 40 to bring said ape tures 38 and 39 in o r ister withh pa sa eways of the hank 28. and 32., as sh wn in Fi 2, for supp yin alarge volum of air to the .5. ice caps. The s em 36 is also providedwith a reduced aperture 42 which may be brought into register with thepassageway of the shank 32, as shown in Fig. 3, for supplying arestricted volume of air to the ice cans. The body 26 and the stem 36are provided with stops 43 and 44 which co-operate for locating the stemin the radial positions shown in Figs. 2 and 3.

The form of my invention shown in Figs; 5 and 6 comprises a double aircontrolling hose usualscrew thread, for connecting the shank to thesupply pipe 18. The shank 47 is also provided with a flange 48 which isclamped against the saddle washer 30, as shown in Fig. 5.

The body 46, of the coupling, is provided with two tubulanoutlet shanks49. and 50, having corrugations 51 for the attachment of hose sections53 and 54 which are connected with the elbow fittings 22 which in turnare detachably connected with the drop tubes 55 and 56 of two separateice cans 57 and 58.

The coupling body 46 isprovided-with a central portion 60, havingpassageways 61 and 62, and enlarged portions 64 and-65 located betweenthe central portion and the'outlet shanks 49 and 50. Said enlargedportions 64 and 65 are provided with cylindrical, or conical bores, orvalve chambers 67 and 68, in which are rotatably mounted cylindrical, orconical valve stems 70 and 71. I apertures 72 and 73 respectivelyjandsmaller or restricted apertures 74 and 75.

' The valvestems '70 and 71 areprovided with handles 76 and 77respectively. Said stems are held in place within the body by washers'78 and nuts 79, shown in Fig. 5. Stops 80and 81 are provided upon thestems and the body for 10- cating the stems radially within the body,with the large or small apertures-registering with the outlet shanks.

The. operation of my invention is as follows:

The air controlling hose coupling is installed in the air circulatingsystem by attaching it directly to the air supply pipe 18, of thesystem. The flexible hose is attached between the outlet shank, ofthe'coupling, and the'elbow fitting 22 leading to the drop tube of theice can;

The volume of air may be controlled by operating the valve stem of theair controlling hose coupling, which coupling is located at a convenientplace within the reach of the operator, for

supplying the full volume of air to the ice cans during the initialfreezing operation. When the block of ice is partially formed with acore hole and the impurities concentrated therein, the core water iswithdrawn and the core is refilled with clean, clear water. ,The valvestem of the air controlling hose coupling is turned to the position toreduce the volume of air, and the freezing process is continued with thereduced volume of air applied.

The form of my invention shown in Figs. 5 and 6 includes a double aircontrolling hosecoupling for the connection of two hose leading to thedrop tubes of two separate ice cans. This form of coupling includes twoseparate valve handles, which are conveniently located at a centralposi-' tion between two ice cans and may be operated at a great savingof time for controlling the volume of air to the cans. I

When the freezing operation is completed the valves may be turned to aposition to shut oh. the flow of air. By changing the position of theelbow fittings 22 from the drop tubes to the air Said stems haveformed'therein large jured, when the can is being inserted orremoved,

is' eliminated.

Various changes in the construction and arrangement of the parts may bemade without departing from my invention.
